To produce a sculpture using the “Lost Wax” casting method takes considerable time and effort which is not fully appreciated just looking at the finished article. An original is made from which a mould is taken. From this mould a wax pattern is produced. The pattern is then coated in ceramic, which, after it has dried, is shock burnt out at 1000 degrees celsius. The wax is lost and a shell remains. Into this shell molten metal is poured.
